2020 Penny Errors - Help Confirm If These Are Die Cracks

By Coin damage do you mean during production or after? I see cracks underneath the lettering in places..

I guess I didn't realize this kind of damage was possible in an uncirculated roll. Weird.

IF you watch videos of coin production, the coins are not carefully placed in bins, they are dropped into in a constant flow. Also the coin years ago used to be handled in $50 bags of coin in banks and $25 bags from the mints. There concern is to make coins. Quality concern is what collectors search for. Looking for the best coins to keep for the future. Other people intentionally damage coins to see if they can make it look like a mint error. When they fail, what so they do with the coin? Spend it, and they turn up here with some one saying, "I found a mint error", but they are just wanting it to be something, that it is not. On the images you posted, did you notice that the EPU devices are incuse? (Below the surface of the design) When these coin takes a hit, if makes an incuse mark on an incuse device. Sometimes it is not as deep as the design, other times it is deeper than the design. I found one that was both:


When you view the image in the horizontal view point it appears the the mark is running behind the devices. But rotating the coin90 degrees, then you can see that is not the case. It show the mark as above the depth and below the depth. This was a coin hit, often called a bag mark. Coin hits from in bags, opened in tills of registers. Damage happens many times during a circulated coins life. But the fact is, that they happened after the strike. So they are not a mint error.
